3 SHEETS-SHEET 2- Zd/IZHEEFEi: I 7' w I, Even/n yfl qkiwm which may beconveniently formed by straps of metal bent to appropriate shape andsecured to the bottom and the outer wall, as by rivets 15.

The second part of the stove consists generally of the annular cover 16having the outer comminglin tube, the protecting hood, the outer wicktube, the wick, and the wick raiser mechanism. The cover 16 is "providedwith a depending flange 17 forming a skirt overhanging the. upper wirededge of the reservoir there-beneath.

Between its inner and outer peripheral portions the cover is shown asprovided with a plurality of angular straps 18 the bottoms of'which. maybe secured to the cover in any approved manner, the upwardly projectingportions 1.9 of the straps having secured thereto a frustoconical hood20, which extends above the tops of the commingling .tubes. The base ofthe hood 20 is substantially flush with the surface of the portion ofthe cover therewithin, such portion of the cover being preferablyprojected upwardly into a ring or corrugation, as shown i at 21. Theinner edge of the cover is projected downwardly, as shown at 22, and theextreme bottom portion 23 is secured to the outer wick tube 24. Thiswick tube projects so a considerable distance above the inner wick tubeand is shown as provided at its top with a series of inwardly projectingfingers 25 constituting a stop for the upper edge of the wick. A slightspace is provided between the downwardly projecting portion 22 of thecover and the portion of the outer wick tube adjacent thereto which sace is adapted to receive the outer commingling tube 26, which may besecured to the parts by peening the overlapping metal parts,

in the manner employed for securing together the inner commingling tubeand the wall 6.

27 denotes a wick, which is inserted in the wic space provided betweenthe tubes 3 and 24.. This wick is preferably of considerablylessthickness than the width of the space between said tubes, and theinner surface of the wick is engaged by a carrier consistin of acylindrical band28 having 'a plura 'ty of outwardly and upwardlyprojecting spring fingers'29 which are adapted to engage the innersurface of the 'wick- The upper end of the wick can be raised until 5gers 2 5. The bottom of the band or skirt 28 is flared outwardly, asshown at 28, and the bottom of the outer wick tube is correspondinglyflared, as shown at 24. It is preferred to flare the bottom of the wick,and this flaring may be secured by slitting the bottom of the wick, asindicated at 27 (see Fig. 3).

The band 28' may be conveniently raised as! and lowered by a pair ofdiametrically opit is brought into engagement with the finposed straps30, said straps having their inner ends connected to the flaring skirt28 and extending outwardly therefrom a suflici'ent distance to clear thebottom of the wick, whence they are projected. upwardly and have securedto their upper ends a pair of straps 31. These straps project throughthe cover 16 and are shown as connected to a band 82 which encompassesthe burnerand boom. About 90 from the point of connection with thestraps 31, an extension of the band is pivoted between a pair of lugs 33secured to and projecting upwardly from the cover, and at a pointdiametrically opposite such pivot the band is provided with an operatinghandle 34, which may be conveniently formed from the metal of the banditself.

When it is desired to extinguish the flame, the frustoconical cover 35may be applied to the stove, the cover being somewhat greater indiameter and height than the hood 2(), whereby it may be dropped oversaid hood, within the band 32, and serve to extinguish the flame, alsoto protect the 9 burner parts therebeneath. The hood will be providedwith a handle 36, for convenience of manipulation;

It will be noted that, in the embodiment of my invention hereto-foredescribed, the reservoir, the inner wick tube, and the inner comminglingtube with its cooperating air controlling caps and'diaphragms constituteone assembly and that the removable cover 16, outer wick tube 24:, outercomrningling tube 26, wick 27, and the wick raising parts, together withthe hood 20, constitute another assembly. The third element which,strictly speaking, is not essential to the op eration of the burner, isthe hood 35, which serves to extinguish the flame and to protect theparts therebeneath from rain when the heater is not in use.

From the foregoing description it will be apparent that I have produceda stove or heater which is extremely convenient of operation whilecorrespondingly simple of construction and economical of production.-

The stove consists essentially of but three parts, including the coveror extinguisher 1 35. When it is desired to fill the reservoir, it isnecessary only to tilt or lift thecover,

as shown in Fig. 3, whereupon the reservoir may be 'filled from a pail,without the necessity-fof a funnel or any special filling appli- 20 anceand without the-necessity ofobserving any particularcare,thus.fa.cilitating the operation of filling the reservoir. In the caseof orchard heaters, where a large number of heaters are in operation atthe same 25' time, the time thus saved is a very considerablesavingitem. Furthermore, the parts are extremelieasily assembled anddisassembled. Should the commingling or burner tubes require cleaning,this operation can be I performed very readily and easily by merelyremoving the cover from the reservoir. This exposes the-outer surface ofthe inner tube 9 and the surface of the outer tube 26, and thesesurfaces may be quickly cleaned by means of a brush or any otherconvenient article.

5 there is. shown a modification of the invention illustrated in thepreceding views, wherein the open topreservoir is provided with aperforated skirt 37 in place of the strap metal legs shown in the otherviews and wherein the commingling tubes 3Sfa'nd" 39 are not secured tothe tops of the I. inner, and outer wick t-ubes, respectively, and

do not form part of the reservoir and the cover assembly respectively.The inner tube is located: above the top of the inner wick tube Theouter tube is seated within an anl 'i'llar space 4Q fsurriounding. theupper end of; the'outer wick tube 24. r The commingli ngl, tubes areconnected by tie rods d1 ex- "t end'ihg th'ereacross, and theoommingling tube assembly may be conveniently centered witlri respect;to the tops of the wick tubes 49,24? and the wick therebetween bymeansofifthe vertical wall 42 defining: the

The stove or heater shown herein. has been found to be extremelyciiicient in operation, not only in the matter of thoroughly heating thesurrounding atmosphere, but in the matter of immunity from smoke andfrom extinguishment and serious interference by drafts. herein, it ispossible to heat an orchard efliciently, without damaging the fruit orwith out the necessity for Washing the fruit in order to removetherefrom the carbon stains which will be deposited thereon by a smokyflame. While the possession of these advantages necessarily makes theheater peculiarly efficient as an orchard heater, 1 Wish to beunderstood as not limiting my invention to this one use, since, becauseof its ciency and freedom fromsmoke, it is applicable to the heating ofwater, the heat ing of garages and other inclosed s aces, and isgenerally useful wherever eflicient heating is desired.

While I have described my invention in detail in connection with themodifications illustrated herein, it is to be understood that I- do notthereby limit my invention to such detailsof construction and that thesedetails may be varied, or departed from, more or less, without avoidingthe spirit of myinvention.

With a heater such as disclosed.
